QUESTION
I am trying to compute the divergence of a vector field:
...ANSWER
Answered 2021-Jun-15 at 15:26Let me 1. explain the reason behind this observation, and 2. how to fix it.
Reason:One needs to be careful about how the data is oriented when computing the divergence (or the gradient in general), since it is important to compute the gradient along the correct axis to obtain a physically valid result.
np.meshgrid can output the mesh in two ways, depending on how you set the index parameter
Index "xy" : Here, for every y value, we sweep the x-values.QUESTION
We have a Adobe AIR desktop application. In the window there is a topbar with some buttons. The central button opens a dropdown popup always at the horizontal center of the screen. Previously there was no scrolbar and the topbar and the popup was always aligned horizontally. But now we have introduced horizontal and vertical scrollbars and hence when the window is resized, the topbar is not at the center of the active window and hence it's not aligned with the popup.
Please check the pictures. The topbar -
The popup -
If the window is maximized in the horizontal side, then the topbar and the popup is aligned.
Now the mxml code -
...ANSWER
Answered 2021-Jun-14 at 11:45This is the default behavior. When you show a popup, you tell it where to be places in .y and .x . When you scroll or resize you effectively change the "center" of the window, but you never inform it that it has changed.
What I would try is adding a listener for window resize and onChange
re-center the popup.

ANSWER
Answered 2021-Jun-11 at 19:01Thanks to the comment from TrentonMcKinney I realized what the issue was:
In my case:
The values in each of my rows are the same, but each row is increasing.
But what I need for streamplot
to work is:
Each row is the same, but the values in each row are increasing.
So I changed indexing = 'ij'
to = 'xy'

QUESTION
CONTEXT
- Created small ticket submission system for a personnel office. Created ability to submit ticket on behalf of another user, such as by a supervisor. Needed one column "CUSTOMER EMAIL" to fill with the email from the actual customer so the system would have one column by which to email the customer.
If SUBMITTED FOR is full, CUSTOMER EMAIL should have SUBMITTED FOR EMAIL.
If SUBMITTED FOR is empty, CUSTOMER EMAIL should have CREATED BY EMAIL.
FLOW
PART 1 (Works fine)
- TRIGGER: Update item/File
- CONDITION: TICKET ID column field is modified
FLOW PART 2 (Problem)
- CONDITION:
"Has Column Changed: Submitted for" IS EQUAL TO "Has Column Changed: Submitted for"
Also Tried
"Has Column Changed: Submitted for" IS EQUAL TO fx: TRUE
Boolean:::
YES
- UPDATE ITEM: CUSTOMER EMAIL (col) with SUBMITTED FOR EMAIL (field)
NO
- UPDATE ITEM: CUSTOMER EMAIL (col) with CREATED BY EMAIL (field)
The FLOW TEST says it works, but when FALSE, doesn't execute the NO "UPDATE ITEM".
Please help!
...ANSWER
Answered 2021-Jun-11 at 17:41Found the problem:
In 2nd condition, was using "Has Column Changed:Submitted For" IS EQUAL TO fx:NULL.
But the value IS updated, even if the value is null, which produces a false positive.
Changed it to: "Submitted for" IS EQUAL TO fx:NULL.
My ignorance on difference between "Has changed" vs is the cell empty or not?
QUESTION
I am building a version of Risk in JavaFX with FXML for school. Now we want to be able to right click a button to decrease the amount of troops in a country and left click it to increase the amount. The left click was pretty self explanatory as it is just an onAction, but how would we check for a right click on a button, through FXML?
...ANSWER
Answered 2021-Jun-11 at 13:45To react to a right mouse button click in javaFX, you would use the onMouseClicked
event handler, and in the MouseEvent
, check for which button was pressed using method getButton
, which will return a MouseButton
with value MIDDLE
, PRIMARY
, or SECONDARY

Answered 2021-Jun-10 at 13:39C# is not a language I've done much with, but I assume you are missing an await
before mqttClient.ConnectAsync(options, CancellationToken.None);

QUESTION
I'm creating a machine-learning program to recognize images that are shown on webcam. I've used Google Teachable Machine to generate the model and it works fine.
The matter I'm having issues with is printing the results of a prediction array, when an element of this array achieves a certain value (if it's equal to or more than 0.9 for an element, print a specific message).
Let's say when element prediction[0] >= 0.9 I want to execute print("Up") as it recognizes the image of an arrow facing up or if element prediction[1] >= 0.9 I'd do a print("Down") etc.
But when I try do that using the if statement I am presented with a
...ANSWER
Answered 2021-Jun-10 at 17:11The problem is that your prediction
has an "incorrect" shape when you're trying to check for each of the values. The following illustrates this:

Depending upon rendering an SVG either as a whole document or as a single element shows differences in rendering.
I created a simple SVG graphic using Inkscape and want to render it using Python. I decided librsvg was the way to go. This is my SVG, saved from Inkscape as "normal SVG" (without Inkscape-specific extensions).
...ANSWER
Answered 2021-Jun-09 at 07:07The culprit is mix-blend-mode:hard-light;
.
I cleaned up the SVG, reset all the translations, but the highlight kept missing. Only after setting the mix-blend-mode
from hard-light
to normal
it reappeared.
